Write the formula for a complex formed between cr3 and 2,2\'-bipyridine (c10h8n2), with a coordination number of 6.

The reaction is:

Cr₃⁺ +3 C₁₀H₈N₂ → [Cr(C₁₀H₈N₂)₃]³⁺

2,2\'-bipyridine is bidentate ligand and neutral. It exhibits two N terminal, thus, it functions as bidentate ligand.

Therefore, three 2,2\'-bipyridine ligand fulfills the six coordination number of Cr₃⁺.

The formula for the complex is [Cr(C₁₀H₈N₂)₃]³⁺

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
